GREAT CAPTAINS ISLAND NATURAL BED. 
Beginning at the point of intersection of a line due east of the Great 
Captains Island lighthouse, with a line ranging northerly and southerly 
over the steeple of the Methodist church in Greenwich and the west end 
of the building standing near the end of the steamboat dock; thence 
running southerly along the last mentioned line about one thousand 
four hundred (1,400) feet to a point of its intersection with a line ranging 
over a gap in the high woods, which are north and east of Reuben B. 
Lockwood's house in Old Greenwich, or Sound Beach, and low water 
mark southeast of the clump on Little Captains Island. This point 
[known as number 521 in Commissioners’ buoy books] is determined by 
the following sextant angles, namely: Stamford lighthouse to Horse 
Neck spire, 62° 19’; Horse Neck spire to Rye spire, 91° 13’; Stamford 
lighthouse to Americus, 59° 17’; Americus to ‘‘ Bloomer,” 59° 24’. 
Thence running westerly on a straight line to a point formed at the in- 
tersection of two lines, one ranging over the north side of the high part 
of the Rye Beach hotel and the south side of the gap in the woods on a 
distant hill in Rye; and the other ranging over the spire of the Second 
Congregational church at Greenwich and a small elm tree on the west 
end of Great Captains Island. This point [known in Commissioners’ 
buoy books as number 421] is determined by the following sextant 
angles: Little Captains Island to Calf, 67° 03’; Calf to Summer House, 
42° 39’; Stamford lighthouse to Mayo, 61° 27’; Mayo to Rye spire, 84° 
06’. The west side of the bed follows the last mentioned range line to 
the high water line on the south side of Great Captains Island; thence 
easterly following said high water line to a point which is due east from 
the centre of the tower of the Great Captains Island lighthouse; and 
thence due east to the point of beginning. The area of this bed is one 
hundred and fifty-two (152) acres.

missioners of Shell Fisheries, for further descriptions of the various 
points used as reference points in the preceding description,
